“It is the most unexpected news but the best news for me. I’m 42 for starters, you get to 40 and you think, that’s it.”

Hayley also revealed that she had suffered a miscarriage before falling pregnant with her son.

She added, “I got to 42 thinking it would never happen. I have had ovarian cysts, but you add everything up and it took my mum seven years to have me in the 70s. I was classed as a miracle baby.

“I thought I will throw myself into work, and I found myself single and 40 thinking that time is gone, people would ask how I was and if I was okay with that and I would say I was career minded but then I met Adrian.”

The star, who appeared in Coronation Street from 2013-2015 as Andrea Beckett, also wouldn’t rule out a return to Weatherfield.

She said, “Why am I not there causing chaos? I see all my friends on Corrie all the time. There is always a chance she could come back and cause some chaos.”
